Specification of Letters Patent.

Patented Nov. 22,1921.

Application filed September 20, 1920. Serial No. 411,516.

To all whom it may concern:

Be it known that I, CHARLES A. Gnoons, acitizen of the United states r esiding in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Carbonator and Draft-Arm for Soda- Water, of which the following is a specification;

This invention relates to dispensing apparatus such as is used in soda water fountains and consists more particularly in certain improvements I have made in the means for carbonating the water and'dispensing the charged liquid.

One of the objects of the invention is to control the carbonating solely by the movements of a single draft arm or dispensing handle, whereby the amount of water and gas delivered to the charging chamber, hereinafter called'the absorption tube, is governed by the amount of carbonated water withdrawn from said tube.

Other objects and advantages will appear in the course of the following description in which reference is made to the accompanying drawing, in whichigure 1 is a perspective view, partly broken away, of a dispensing apparatus or soda fountain, equipped with my improvements.

Fig. 2 is an enlarged view,-partly in section, of' the arrangement of parts constituting my invention.

Fig. 3 is a vertical section of one of the absorption tubes shown in Fig. 2.

Fig. 4 is a front view of the dispensing faucet and draft arm.

Fig. 5 is a vertical section of the same on the line 5-5 of Fig. 4.

Fi 6 is a cross section on line 6-6 of Fig. 5 showing the arrangement of ports in the valve seat.

Figs. 7, 8 and 9 arediagramsshowing the position of the ports in the valve in-its different positions.

Fig. 10 is a cross section on line 10-10 of Fig. 5.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings,

1 represents the base upon which stand the absorption tubes 2 and the volume tube 3,

and 4 the standard supporting the valve casing 5. 6 is the handle or draft arm mounted on the square shaft 7 of the valve 8, the valve itself being slidable on the other end of said shaft so that it can be pressed against its seat by a screw 9 provided with means to secure it in adjusted position, such as a spring arm 10 engaging serrations formed on a washer or head 11 carried by said shaft.

13 is the discharge tube of the faucet into which open the outlet passages 14in the valve casing (see dotted lines in Fig. 5) and depending 1n which is the gas vent tube 15, carrying the cup 16 and communicating with the vent port in the valve casing heroinafter described. The volume tube 3 com- 20 and the lower chamber 21 separated by the partition 22 in which is an opening 23 closed upwardly by a ball check valve 24.

25 is the water-supply pipe leading to the upper chamber 20 and containing an upwardly closing check valve, the casing of which is shown at 26. .27 is a gas-supply pipe leading from the valve easing into the top of the volume tube 3 and closed upwardly by a ball check-valve 28. 29 is another gas-supply pipe leading from the valve easing into the lower chamber 21 of the volume tube, where its end is bent and perforated as shown at 30, see Fig. 2. 31 is a branch pipe leading from pipe 29 into the top of said lower chamber 21 and provided with an outwardly closing check-valve, the casing of which is shown at 32.

33 is the gas-supply pipe leading from the gas tank 34, see casing, and 35 is the discharge pipe from the bottom of the volume tube 3 to the first of the absorption tubes 36, six of which are shown in the drawing. These tubes contain a plurality of screens such as shown at 37 in Fi 3 and one or all of them may also contain the cones 38, closed at their bottoms by screens 39, to assist in the mixing of the gas and water, that is, in the charging of the water. These absorption tubes are con nected in series b the pipes 40 running from the bottom 0 each of them to the top of the next succeeding one, as shown in Fig. 2, and from the last of the series (the number' of which may be varied as desired) runs the pipe 41 to the valve casing.

The valve casing 5 contains the passages *ig. 1, into the valve.

. ted

or ports 42, 43, 44, 45, 46 and 47 and the valve 8 contains passages or ports 52, 53, 54, 55, 5e, 57 and 58.

49 is the usual fixed washer between the valve and its seat in the casing.

The gas supply pipe 33 communicates with port 42 in the valve seat which when the valve is in open position coincides with port 52 in the valve connected with port 53 in the latter and port 53 coincides, in the valve open position, 43 of the casing which leads to pipe 29. At this time the charged water in pipe 41, which leads to port 44 in the seat, passes out through port 54 in the valve and con necting passage to port 55, which coincides with port 45 in the casing leading to discharge outlets 14. The port 46 in the casing leading from vent tube 15 coincides at this time with port 56 in the valve connected by a passage with port 57 in the latter, coinciding with port 47 in the seat,'which leads to pipe '27, letting gas which may have accumulated in the upper chamber 20, but which is not under pressure, escape into the vent tube 15. 7

When the valve 8 is in closed or shut position as shown in Fig. 5, the gas through the pipe 29 leading to the lower chamber 21 is shut off. The gas inlet pipe 33 communicates with the port 42 in the valve seat which in this shut osition coincides with the port 58 of the va ve disk 8. The gas then flows through said valve 8 to port 52 of the valve disk, which communicates with the port 47 of the valve seat and then through pipe 27 to the upper chamber 20 of the volume tube 3; and forces the Water therein through the ball check valve 24 down into the lower chamber 21. In this position all other ports in both valve seat and disk are closed. The water in the volume tube is supplied through the pipe 25 which has a check valve 26 therein, as before stated.

60 represents screens to support the ball check valves 24 and 28.

To briefly recapitulate the operation:

. hen the valve is opened, gas is admitinto the lower chamber 21, forcing the water therein into the absorption chambers and charged water therefrom out of the faucet. At the same time gas from the upper chamber'is vented into the faucet. When the valve is closed, gas is admitted into the upper chamber and forces the-water therein into the lower chamber.

It will now be apparent that I have devised a novel carbonator and draft arm for with port v soda Water which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice, satisfactory and reliable results, it is to be understood that such embodiment is susceptible of modification in various particulars Without departing from the spirit or'scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a dispensing apparatus, the combination ofan absorption tube, a volume tube divided into upper and lower chambers, a check valve between said chambers, a gas pipe leading into the upper chamber, a gas pipe leading into the lower chamber, a pipe connecting said lower chamber to said absorption tube, a water supply pipe leading into said upper chamber, and a valve controlling both the admiss on of gas to said chambers and the discharge of carbonated water from said absorption tube.

2. In a dispensing apparatus, the combi-' nation of an absorption tube, a volume tube divided into upper and lower chambers, a check valve between said chambers, a gas supply and vent pipe leading into the top of said'upper chamber, a branched gas supply pipe leading into the top and bottom of said lower chamber, a pipe connecting the bottom of said lower chamber to said absorption tube, a water supply pipe leading into said upper chamber, and a valve controlling both the supply of gas to said volume tube and the discharge of carbonated water from said absorption tube.

3. In a dispensing apparatus, the combination of a plurality of absorption tubes connected in series, a volume tube divided into upper and lower chambers, a downwardly opening check valve between said chambers, a gas supply pipe leading into the top of said upperchamber, means to supply. water to the latter, a gas supply pipe leading into said lower chamber, the latter being connected to the first absorption tube, and a discharge pipe leading from the last absorption tube, and a handle controlling the flow in all of said i es.
